The Regression Equation Questions with
Correct Answers 2025
Simple linear regression: - correct answers-Analysis where yo attempt to find the line that best
estimates the relationship between two variables
Dependent Variable - - correct answers-Y
Response Variable
Independent Variable - correct answers-X
Predictor Variable
Intercept coefficient - correct answers-B0
Slope Coefficient - correct answers-B1
Error term - correct answers-e= y - y^
Population (Theoretical) Equation - correct answers-y= B0 + B1x + e
Sample (Empirical) Equation - correct answers-y^= b0 + b1x
Scatterplots - correct answers-vertical axis - y
horizontal axis - x
Uses of regression models - correct answers-1. Provide insight into relationships - used for testing and
interpreting the slope
2. Estimation - used to estimate the average value of y for a given level of x
3. Prediction - used to forecast the next value of y for a given value of x
Correlation coefficient - correct answers-R
between -1 and +1
shows strength
